DISPENSING CARBONATOR FOR BEVERAGES.

Applicationvled May 5, 1919. i Serial No. 294,745.

To all whomt may concern." f .l Be it known that I, JOHN E. Hines, acitizen of the U-nited States, and a resident of Ardmore, county)f'l\[ontgomery, `State of Pennsylvania, have invented certainImprovements in Dispensing Carbonatorsly for Beverages, of which thefollowing is a specification.

The obj ect of my invention'i's to provide a dispensing apparatus forbeverages with a carbonatonso that uncarbonated liquid can be placed inthe apparatus and carbonated as it is drawn from the receptacle.

In they accompanying drawings:

Fig. 1 is a vertical sectional view of my improved carbonator forbeverages;

Fig. 2 is a sectional plan view on the line 2-2, Fig. 1;

Fig. 3 is a sectional plan view on the line 3 -3 u' Fig. 4 is anenlarged sectional view illustrating in detail the 'construction ofthecarbonator, and p .y

IFig. 5 is a view showing` a-refrigerating coil surrounding thecarbonating chamber.

lis a container made in the formv of a barrel in the present instance,having a bottom 3 and a top 2. The top' hasa removable section 29, asshown, for the introduction of ice. 'Ihe containervhas lining 28 andbetween the lining and the body of the container is a filling 26,preferably of cork. rIhe top and bottom are also lined and filled,asshown. Located within this container is a vessel 4 closed at thebottom and having a removable cover plate 5. Adjoining lthis vessel is arcarbonating device consisting of a tubular chamber 6 of thesame lengthas the vessel 4 and, in the lpresent insta-nce, closedby the same plate5.

7 is anipple attached to the cover plate 5 and extending through the top2 of the barrel. The vessel. 4`is filled througl'i this ni'p ple, whichis closed by a screw cap. 'EX- tending from the nipple is a strainrn Si.

The space 30 surroundin the vcsselft and chamber 6 is filled with icethrough the opening in the'to'p closed'by the section 29., as theliquid` must be cool. y 10 is a pipe'leading from va gas pressure tank,shown by dotted lines in Fig. 1,*which Aextends through-the space 30 andis connected to the upper "part of the vessel 4. The chamber 6 isconnected to the vessel 4 through a pipe 11 in which is a reducing valve12 so as to keep the pressure in the carbonating chamberbelow that inthe vessel 4. Communicating with the lower portion of the vessel 4 is anoutlet pipe 13, which is coiled around the'chamber 6, as shown in Figs.1 and 4,"and is connected to a spray nozzle 14 located in the upperportion of the chamber 6. This nozzle has a valve 15 which is connectedby a rod 16 with a ball iioat'l in theflower portion of the chamber 6.This float regulates the y.

amount of liquid passing the carbonator.

18,- 18 area series of perforated disks, whichtend to break up the flowof liquid so that it will, be fully carbonated by the time -it reachesthe bottom of the carbonating chamber. Communicating with the bottom ofthis chamber is an outlet pipe 19 having a spigot 20. y

`.The rod 16, connected to the valve, passes through enlarged openings22 in the disks 18 and there is a "bonnet 23 on the rod above each disk,which prevents the liquid running -down the rod and through the openings22. Bythis construction, thel several spacesbetween thedisks containgasof the samefpressure, while the liquid must..pass through the smallperforations inthe disks 18, accumulating in the bottomof thecarbonator. The valve of the spray nozzle is the ordinary needlevalve/and the nozzle is preferably arranged so as togivey a twirlingaction to the spray. y

I preferably provide a pressure gage 24 'connected by a pipe 25 with thepipe 11 between the reducing` valve 12 and the carbonating chamber 6, sothat the attendant Igan ascertainthe pressure in the said chamer. i

vWhere a"refrigerating coil 27 is used, as

chamber 6in close contact with the liquid coil 13,*and I may return thecoil to form a double coil` if found desirable, as it will be understoodthat, the liquid must be cool beforeit can be properly carbonated. Thecoil is connected to any .suitable refrigerat ing apparatus. p p

Inoperation, the liquid to be carbonated, as `a Vfountain beverage forinstance, is poured into the vessel'4 through the filling openingin thenipple. 7. Gas is then admittedtol this vessel through the pipe 10 atabout 3() lbs. pressure. The'reducing valve 12 in the pipe 11 is set soas to reduce the gas passing through the pipe from the vessel 4 into thecarbonating chamber 6 to about in Fig. 5," I preferably coil it aroundthe 20 lbs.; so that when the spray valve 14 is opened there will besuthcient pressure to cause the liquid to be sprayed through. the nozzleintol the carbonating chamber. The finely divided liquid as it falls'will pass through the perforating disks 18 and become thoroughlycarbonated by the time it reaches the bottom. As the liquid accumulatesin the bottom, the iloat will rise and Will close the valve in the spraynozzle and the flow of liquid will cease. When the spigot 2O is open,then the liquid in the bottom is removed and the float is lowered andthe valve in the spray nozzle is opened, which will allow the liquid tobe again sprayed into the carbonating chamber until theliquid in thebottom of the chamber-rises to a certain height; which will close thevalve.k

Vhile I have shown the container in the form of a barrel; it will beunderstood that it can be made of any suitable material and form. The.barrel construction is especially adapted for use Where the dispensingapparatus is installed in fair grounds, and similar places, but whereused at a soda fountain a more attractive and ornamental structure maybe provided. In some instances, the vessel 4f may be located in onecontainer and the carbonating chamber may be located in anothercontainer without departing from the essential features of theinvention.

I claim:

2. The combination of a container; a vessel located in the container; acarbonating chamber at the side of the vessel and also A in thecontainer; a pipe forming communication with the upper end of the vesseland the chamber; a reducing valve in the pipe; a pressure pipecommunicating with thel vessel; a spray nozzle` inthe carbonatingchambei? CQmIXlrunicating with the bottomof the vessel; a valve in saidspray nozzle; a oat attached to the valve located in the lower portionof the carbonating chamber; an outlet pipe at the bottom of thecarbonating chamber so that as the liquid is drawn off thc level of theliquid in the carbonator is lowered and the valve of the spray nozzle isopened, allowing additional liquid to be sprayed into the carbonatingchamber.

3. The combination in a ispensing carbonator for beverages, oit' acontainer; -a vessel in said container; a carbonating chamber of lesssize than the vessel7 also located in the container; a gas pipecommunicating with the upper portion of the vessel; a second pipeconnecting the upper portion of the vessel with the upper portion ofthecarbonating chamber; a reducing valve in said second pipe; a third pipeleading from the bottom of the vessel and lcoiled around the carbonatingchamber; a nozzle within the upper portion of the carbonating'chamberconnected to said third pipe; a valve in said nozzle; a float connectedto the valve and arranged to be raised and lowered according to theamount of liquid in the bottom oit' the oarbonating chamber; and aseries of perforated disks in the carbonating chamber over which theliquid passes from the nozzle.
